@Ciufer As an aside, if you currently have any files in ConfigOverride, in Documents > Electronic arts > The Sims 4, please remove them.
Just as a test, try lowering the game's fps limit. Open Options.ini, inside Documents > Electronic Arts > The Sims 4, search for frameratelimit , and change it to 60. The game should honor the limit regardless of any other settings.
If that doesn't help, try switching to DirectX 9 mode. You'd have been using it before the latest patch, unless you opted into DX11, but it's worth trying again now. DX9 is an option with the other graphics settings.
If that doesn't help either, please try playing in a clean boot:

The one service to leave enabled is the EABackgroundService, which the EA App needs in order to run. Disable the rest as described.
When you reboot your computer, go through the Task Manager's background processes list shutting down any service that doesn't absolutely need to be running, for example anything from MSI Afterburner to RGB software might still be enabled. If you accidentally kill a critical process and it doesn't restart on its own, just reboot your computer again.
Don't open anything other than Sims 4 and the EA App while testing, not even a browser window.
It's worth repeating the test with your computer offine as well. You can sign into the EA App and set it in offline mode, then disable wifi and/or disconnect the ethernet cable before pressing Play.
@Mitsu2040 Please test with no mods or custom content, and nothing in ConfigOverride. If you still get crashing, provide a dxdiag.
